    "Sharp minima can generalize for deep nets" or why the community does not learn
    Every few months in machine learning, we have this recurrent debate about the role of sharpness in generalization. The short story is that the solutions found by SGD seem to be in "flat" areas of the...

    For the future PhD students that are deciding in these days which offer to accept, let me give you a very simple advice: Avoid choosing a**holes as supervisors. It does not matter how famous they are or how prestigious is the school, you'll regret it and they don't deserve you.

    New blog post: Neural Networks (Maybe) Evolved to Make ADAM the Best Optimizer For the first time, I wrote a blog post without math :) I discuss a *conjecture* I have regarding Adam and the way the deep learning community produces new ideas

    It is now official: I got the @NSF CAREER award for "Parameter-free Optimization Algorithms for Machine Learning"! Super happy :) Soon, I'll tweet about an exciting new result about parameter-free algorithms for non-convex functions: I had this idea writing this proposal :)

    This is a turning point: I just proved a complex math result useful for my research using an LLM. I am not sure if I should be happy or scared...

    Dear PhD students with a submission to @NeurIPSConf, soon ~20% of you will receive a desk reject. Here some suggestions to deal with it in a healthy way. First, this is not personal: a paper written by you was rejected, not you. Keep your self-worth unlinked from your work. 1/5

    As promised, we put on Arxiv the proof we did with Gemini. arxiv.org/pdf/2505.20219 This shows that the Polyak stepsize not only will not reach the optimum, but it can cycle, when used without the knowledge of f*. Gemini failed when prompted directly ("Find an example where the

    Unpopular opinion: "Optimization for Deep Learning" should be removed as a subtopic in ML conferences. Numerical optimization is estabilished field: we don't need a worse variant of it with algorithms justified by "intuition", rarely converging, and not properly evaluated.

    Given that even @BU_ece changed my title on the website, I guess it is now official: I have been awarded tenure and promoted to Associate Professor This was a long and stressful journey, but I f*cking did it!!! 💪🥳🎉
